The device in order to remove the fields magnetic in the form of a bubble without application of a magnetic field gradients, but of fields coplanar modules

摘要

P device for displacing the fields in the form of bubbles in a magnetic support for the application of a variable magnetic field in the time, but which is uniform in the space. / p & & p & the fields of pairs of lines of bloch in their magnetization of the wall can be moved by a cyclic process where the lines of the bloch switch between two configurations of a material that is asymmetrical in response to the field of variable. / p & & p & application to the bubble memories. / p
